The act of going to someone's house then proceding to take the garbage bag out of the can then taking a massive dump in the can. After this you can top it off with some throw up and urine to make a thick mess. Lastley you close the lid leaving to mix to soak for preferabley 2-3 hours in a hot climate. Hopefully this mix will cause who ever opens the can to also throw up in it incressing the stench. Similar to a mexican hot pocket

Dude i gave Ryan a trash can surprise after he went to sleep so it will be able to sit for a while.
